BYOC tonebender mkII fuzz, 2008 version with Philips OC75 germanium transistors

This one starts to crackle when the fuzz dial is at noon and further. Is this normal or is there something wrong (bad transistors?). I actually have only two possible settings: the fuzz knob fully up or the fuzz knob fully down.

i dont think its supposed to sound like that

[bopplayer]

Sounds like i'm getting a hair cut.

[axeslinger013]

That was built wrong...

[caseycollis]

The germanium transistors are very temperature sensitive. That's the sound they produce when they get too hot.

Ouch! Bias that thing, brother! :S:D

Thats how my broken rocktron booster sounded lol

1) Bias it, i think there's a trimpot for the third trannie. Just tinker about with it until you think it sounds good. Don't listen to people saying it must be exactlt 4,5 volts, i think they usually sound best around 5 volts or even more.

2) if you haven't used transistor sockets you may have cooked the transistors. And that means that the trannies are now junk. I hope you used sockets...

Is there a bias trim pot in this? You might have to bias it correctly to get rid of the buzz....I have the byoc fuzz face clone and it has that.

[ckyvick666]

there is a wiring problem on the fuzz pot or a problem with the transistors. were you able to bias the transistor to 4.5v?

[Ombrenuit]

actually I like the crackle sound! that's why I want to build one lol

[rsl84416]

agreed

[belgion75]

Yeah , Lemon and palmz are right. I just finished building a byoc fuzz (first time DIY) and had the same thing... for 5 minutes.... until I adjusted the bias trim.... so..... bias that..... yeah...
